Title: Manufacture of thermoelectric material
Inventor: ENDO ISAO
IPC: H01L35/16
Filed: 1995-12-19
Abstract: PROBLEM TO BE SOLVED: To obtain crystal grains having texture or random direction, by filling a capsule can with material powder, and isotropically hot-pressing the powder after degassing and tight sealing. SOLUTION: Raw material is stoichiometrically weighed, sealed in a quartz tube or the like, melted and cooled, and the obtained ingot pulverized. A capsule can is filled with the mixed powder. After degassing and tight sealing, HIP is performed by using Ar gas as pressure medium. The density ratio designates the ratio of the density of a sintered article to the density of a perfect dense body. Since the capsule can is pressurized with a gas pressure having isotropy, the compressive force can be applied to the interior of the can. Thereby it can be unnecessary to increase the treatment temperature of the treatment period, when the product size is large. Hence a product of high density can be obtained without enlarging crystal grains. The crystal grains of an obtained sintered article have a texture of random direction, and the bending strength has no anisotropy.  Thereby, when slice-working is performed, fracture and cutout are not generated in a slice-worked article.

Filed: 1989-12-20
Abstract: PURPOSE:To control a relevant station by transferring an infrared ray remote control signal to an object station via an information transmission line when the content of the signal is decoded even while the received signal is a control signal addressed to other station. CONSTITUTION:When a remote control signal is inputted from a light receiving means 101, after the signal is converted into an electric signal and transferred to a system control means 122 of the station and inputted to a data code processing means 103 simultaneously. Then whether the received remote control signal is able to be demodulated, the content is able to be decoded, the signal is addressed to stations other than its own station or the standard command corresponding to the content of the remote control signal exists is checked. When all the conditions above are 'YES', a command frame comprising the relevant standard command is sent to the relevant station via an information transmission line. Thus, a remote control transmitter added to each station is in use to control the basic function for the standard command.

Title: Variable pole single-phase induction motor
Inventor: KOU KENMIN
IPC: H02K17/06
Filed: 1996-12-11
Abstract: PROBLEM TO BE SOLVED: To make the number of poles of a stator changeable by switching the connecting wiring of stator windings by utilizing a switch element. SOLUTION: A relay switch R is constituted of traveling contacts (h) and (i), fixed contacts (j), and three moving irons (k). The moving irons (k) move together in the vertical direction in accordance with the energized state of an exciting coil. When two-pole operation is made, the irons (k) move upward and form a two-pole rotary magnetic field in which one N pole and one S pole appear and the rotor of a single-phase induction motor can smoothly rotate at the vertical boundary between first main windings 9A and 9B. When four-pole operation is made, the ions (k) are moved downward by means of a relay device utilizing a force of inertia and form a four-pole magnetic field in which two N poles and two S poles appear and the rotor is rotated by a half-rotation which is obtained when two-pole operation is made.  Therefore, the slot area can be reduced and the workability can be improved, because two-pole main windings and four-pole main winding can be used commonly.

Title: Resist pattern forming method
Inventor: KASASHIMA MASAAKI
IPC: H01L21/027
Filed: 1990-11-29
Abstract: PURPOSE:To make it possible to easily form a resist pattern provided with a very fine aperture part by a method wherein the latent image of a target aperture part and the auxiliary latent image of the aperture part, having the prescribed area and used to accelerate the flow-in of developing solution to the resist part where the latent image is formed, are formed. CONSTITUTION:A resist film 43 is formed by having a silicon substrate coated with negative photoresist, and a photo-exposing operation is conducted thereon by a contact aligner using a photo-mask 31. A slit type latent image 43a is formed on the part which comes in contact with the light-shielding section 33 of the photo-mask 31, and an auxiliary latent image is formed on the part which comes in contact with an auxiliary light-shielding section 33. As the auxiliary latent image has a certain degree of area, the resist part where the latent image is formed is excellently removed by the developing solution while it is being developed, and a recessed part is formed. As a result, a developing solution flows in from above the resist part where the latent image of aperture part is formed, and also a developing solution flows in from the lateral direction through the recessed part. Consequently, a resist pattern, having a very fine aperture, especially a slit type aperture, can be formed easily.
